Used as a key intermediate in peptide synthesis and pharmaceutical manufacturing, particularly in the protection of amino groups during multi-step organic reactions. Its benzyloxycarbonyl (Cbz) and tert-butyl ester functionalities allow selective deprotection, enabling controlled assembly of complex molecules. Commonly employed in the production of active pharmaceutical ingredients (APIs) where orthogonal protection strategies are required. Also utilized in the development of protease inhibitors and other bioactive compounds due to its stability under various reaction conditions and ease of removal under mild acidic or hydrogenolytic conditions.
